Ramirez is accused of driving while intoxicated at around 8:30 p.m. on April 25, 2011 in the 3600 block of Cleveland in Groves. Court documents allege he struck two teens - one on a bicycle and another on a skateboard.

Per the plea deal, Ramirez would be placed on 10 years' probation in each of the cases. His probation would be deferred in the intoxication manslaughter case, meaning a conviction would not appear on his record if he successfully completes probation, Assistant District Attorney Clint Woods said.

A conviction would appear on his record for the intoxication assault charge, Woods said.

If Walker does not follow the plea agreement, Ramirez faces up to 20 years and 10 years, respectively, on each of the charges.
